MACHINE FOR MEASURING AND VENDING LIQUIDS.

Application filed September 10, 1921. Serial No. 499,598.

To all whom it may concern:

Be it known that I, CLARENCE A. Ross, acitizen of the United States, and a resit dent of the city of Joliet, in the county of Will and State of Illinois, have invented certain new and useful Improvements in a Machine for Measuring and Vending Liquids; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being hadto the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification. This invention relates to pumps of th sort which are used in dispensing gasoline 'for automobiles.

It is an object of this invention to combinewith such a pump a device which shall punch, cut 011' and deliver a ticket from a roll of tickets so that the amount of gasoline delivered shall be indicated by the punch mark on the ticket.

Itis a further object. of this invention to interlock a pump operating mechanism 2 and a ticket delivering mechanism so that a. ticket cannot be punched and delivered unless gasoline is actually pumped. It is further an object of my invention to provide means for causing the ticket to travel past the punching mechanism by the motion of the-pump operating mechanism and means for causing the ticket to be punched, severed from the strip of tick- 'ets and delivered from the machine by the motion of an auxiliary'handle.

Other and further important objects of this invention will be apparent from the disclosures in the'dra'wings and specification.

The invention -(in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawin 5:

Figure 14 is a section taken upon the line 1%1=L of Figure 5.

Figure 15 is a plan view the. strip of tickets. As shown on thedrawings:

The gasoline, pump 1' is driven in the usual way by crank 2. The crank operates through a train of gears 3 to work the rack of a portion of bar 4 by which the piston of the pump is operated. The spindle 5 carrying the last of these gears is prolonged to enter a housing 6 which is an offset from the main housing 7 enclosing the ticket cutting and punching mechanism. ,The offset housing 6 encloses a pair of gears S by which the spindle 5 drives the largergear 9. The gear 9 is keyed to a shaft 10 and a. ratchet clutch member 11 is keyed to the same shaft. A spring 12 between the gear 9 and the clutch member 11 tends to keep this member in contact with a clutch member 13. i

The clutch member 13 is provided with ratchet teeth 14 upon the edge thereof and with teeth .15- upon the side face thereof which cooperate with ratchet teeth 16 upon the member 11. A pawl 17 mounted in lugs 18 upon'the wall of the housing acts to prevent the clutch member 13 from rotating in one direction, namely, the direc tion in which the'side toward the reader in Figure 5 would move upward. A spring 19- is provided to cooperate with the pawl. Thus when the pump handle 2 is operated in one direction, the gear 9 will rotate idly merely driving the teeth lG on the clutch I 5 the lug 39 toward the 55 the motion of the tool.

member 11 over the teeth 15 on the clutch member 14. The spring 12 permits the 10: The sleeve carries a pair of sprocket wheels 21. The teeth of these sprocket wheels. are adapted to mesh with holes 22 1 upon theedges of a strip of tickets'23. The

strip of tickets is coiled upon a spool 24 siup ort ed in stirrup 25 as shown in Figure a roller 26 and across the top of the housing 15 7 to a roller 28. From this roller it descends through a slot 29 in the upper edge of the housing 7 and is received between two plates 30 and 31. r 1

A Integral with the sleeve 20 is a wheel 36 20 at the left of the left hand sprocket vwheel 21. This wheel as illustrated in Figure 11,

has a notch 37 in the peripherythereof and dog 38is provided with -a lug. 39 adapted to cooperate with the notch. The edge of shaft sleeve 20 is bevelled as shown in Figure-11. The dog 38 is spring pressed towards the wheel 36 by the spring 40 which is curled about thepivot of the dog where the dogis mounted on 30 lugs 41 upon the housing 7. The dog 38 v has a second lug with a notch 43 ina wheel 44. j As shown in dotted lines in Figure 8, the Ifotch 43 is not bevelled at either side so that the lug 42 acts to hold the wheel 44 from rotation in either direction. The wheel 44 is integral with a sleeve 45 mounted upon the shaft 10. The wheel 36 has'a lug 46 and the wheel 44 has a with each other as illustrated in Figure 5 except when the sleeve 20 is rotated by the .gear 9. p

Besides thewheel 44 upon the sleeve 45 there is another wheel 48 upon the periph- 45 cry of which there is a Iug'49. which has a bevelled edge adapted to coact with the bevelled end of a rock arm 50. This arm is keyed to a shaft 51 mounted in lugs upon the plate 31. At the other end of the shaft 51 is a rock arm 52 approximately arallel tothe plate 31. The lower end of t is arm has a recessed boss 53in which is pivoted a unching tool 54; holes 56 and 57 in the plates 30 and '31 respectively provide for The rock shaft 51 and the rock arms 50 and 52 are biased away from the position in which the punching tool pierces the paper by a spring 58. 4 The sleeve '45 also carries a ratchet wheel 60' which-is retained by a pawl 61 pivoted to the side of the housing.v The pawl is held against the ratchet w eel 'by a spring 62. The sleeve extends through the housing and has on the end of-it external to the housing a hub 63 for a crank 64.

rom this spool the strip is led up overfastened thereto a 42 adapted to cooperate lug 47 which contactpiece 69 the end ofwhich cooperates with the notch 65' and is forced out of this notch when the wheel 48 is rotated. A spring presses the tail piece 69 against the wheel 48 and the main arm of the lever 66 toward the bottom of the housing. The end of the lever 66 opposite shaped end 71. \Vhen the tail piece 69 is the tail .piece has a tooth' lifted out of the notch 65 this end 71 will engage between 'the teeth of the gear 9 and prevent rotation of the handle 2.

The clutch member 13 has upon its face opposite the clutch teeth a cam 72 which operates against the lug 7 3 upon the short; arm 74 of a lever pivoted at7 5. The sup-- port'for this pivot'is a bracket 76 secured to the plate 31 near the lower edge thereof. The horizontal part lug 77 and the short arm 74 has a stud '7 5 surrounded by a cushioning of india rubber which contacts with the lug 77 to bring the short arm of the lever gently to rest, in the position illustrated and to produce a tendency of the lever to rebound after the lug is strucka, The long arm 78 of the lever has knife 79. Suirounding thestud upon which this lever is pivoted is a spring 80 by to cutting position. -Below as shown at 81, a notch 82 being provided forthe reception of the cutting edge of the knife in its extreme position. The plate 81 is paralleled by a plate 83in the same plane with the plate 31.' This plate is fastened'to the bottom of the housing as indicated at 84, preferably the outlet 34 of the bottom of the housing is. bevelled to meet the lower edges of the plates 81 and 83.

When the device is assembled, the top and bottom portions of the housing are fastened togetherby av rod 85 which is secured in place by a ad lock 86. Unauthorized ta'mpering wit the", mechanism is thus prevented.

In the operation of the device the crank 2 is rotated first in one direction and then in the opposite direction, to operate the ump through the'rack bar 4. Consequentfiy the spindle 5. and the gear 9 are rotated rst inone direction and then in the other.

As the gear 9 is rotated in one direction the of this bracket has a which the knife is moved the knife, the plate 30 is continued V in the opposite direction the clutch member 11 drives the clutch member 13 and so drives the sprocket 21. The distance through which these sprockets are moved, depends upofi the travel of the pump handle 2 and so upon the amount of gasoline delivered.

When the pump handle 2 comes to rest,

I wrong direction.

due to the pump having come to the end of its stroke, the clutch member 11 will no longer drive the clutch member 13 and the sleeve 20 will come to rest, the sprocket 21 having dragged the strip of tickets a correspondingdistance. As illustrated in Figure 15, there is on the tickets a row of numbers to indicatevthe number of gallons delivered by the pump. The strip 23 will come to rest with the number corresponding sleeve 20 forced the lug 39 out of the notch' 37 and so by moving the dog 38 lifted the lug 42 out of the notch 43. This left the sleeve 45 unlocked so that it may now be rotated. V

-The operator then manipulates-the crank 64 and so rotates the sleeve 45.. The pawl-61 prevents rotationof the crank 64 in the The first movement of the crank will cause the lug 49 to pass under the end 50 of the rock arm and so rotate the rock shaft 51, Fig 8. This will rotate the rock arm 52 and drive the tool 54 through the holes 57 and 56' perforating the ticket 43 as indicated at 90 in Figure 15. Further motion of the crank 64 and so of the wheel 48 will cause the notch 91 behind the end 50 of the rock arm to snap over the side of the lug 49 under the influence of the spring 58. This will withdraw the cutting tool 54 from the position in'which' it traverses the paper.v

Still further rotation of the crank 64'will make the lug 47, on the wheel 44 contact with the lug '46 on'the wheel 36. As the rotation of the crank 64 is continued. the sleeve as well as the sleeve 45 will be rotated thereby. Consequently the sprocket 21 will be rotated and the strip of tickets will again travel downwards. When the rotation is nearly completed, the cam 72 will contact with the stud 73 Fig. 14 and move the lever 78 counterclockwise as shown in Figure 12 and the knife 79 moves away from the paper against the influence of the spring 80. y

\Vhen the cam 72 gets past the stud 73 the straight edge of the cam will permit the lever 7 8 to snap under the influence of the spring 80. The knife .79 will pass beyond the position illustrated in Figure 5 so far that the covercushioning the stud- 75 will be compressed against the lug 77. During the moment of this compression, the edge of the knife will be beyond the paper in the recess 82 at the beginning of the continuation 81 of the plate 30. The elastic force of the rubber cushioning on the stud 75 will return the knife from this extreme position to the position illustrated in Figure 5,, in which position it does not prevent travel of the paper.

The ticket which is severed by the knife already has its lower end in the guideway 35, this end of the ticket having passed down between the plates 81 and 83 under the influence of the sprocket 21." hen it is severed by the operation of the knife described, the ticket will therefore; fall through the guideway and the operator may remove it from the open end 92 of this guideway. The first motion of the crank 64 causes the wheel 48 to move and so lifts the tail 69 of the lever 66 out of the notch 65. This causes the end 71 of the lever ,66 to enter between two teeth of the gear wheel 9 and manipulation of the crank 2 is therefore prevented until the operation of puinching and delivering a ticket is comete p \Vhen the crank 64 has completed a revolution the spring will cause the dog 38 to move so that the-lug 42 enters the notch 43 and the sleeve is locked against further movement. During all of the latter part of the revolution of *the crank 64, the lug 47 has been driving "the lug 46 and so turning the sleeve 20 against the friction produced by the spring 12 forcing the bev- -elled teeth of the clutch members 11 and 13 together. Consequently when the crank 64 is brought to a stop by the lug 42 snapping into the notch 43, the. lug 46 will stop in a definite place. The next ticket in the strip 23 will therefore be moved to the proper place. in the next operation and will in its turn be correctly punched and severed.

The crank 64 cannot again be moved until the crank 2 has been moved so that the wheel 36 has turned and lifted the dog 38. Thus it is not possible to extract a second ticket g is not however necessary that the length of theticketcorrespond to a complete up and down stroke of the piston of the .pum even at its maximum capacity, but pre erabty the ticket is made several times this length so that if the operator desires to deliver upon one ticket amultiple of the maximum capacity of one stroke of the pump, he can 7 more gasoline at one time than corresponds till (ill

to a complete revolution of the sleeve 20, it

i would be indicated by the delivery of a ticket which did not have any punch mark. A. record of this fact can be obtained by serially numbering thetickets as indicated at 93. If the operator should undertake to de- V liver any gasoline without manipulating the crank 64 and so punching the corresponding ticket this fact would be indicated by a skip in the serial numbers of the tickets which the operator would turn in or by the presence of an unpunched ticket which would cause the operator to be charged with the maximum quantity of gasoline called for by the ticket.
